    摘要: An ultra-high-vacuum (UHV) cell includes an integrated guide stack (IGS) as part of a boundary between an internal vacuum and an external ambient. The IGS is formed by bonding together plural integrated guide components (IGCs). Each IGC includes (prior to the bonding) electrical and/or electro-magnetic (EM) guides defined within a bulk material such as glass or silicon. The electrical guides can be, for example, conductive paths or vias, while the EM guides can include microwave or other RF guides, optical fibers and/or paths along which an index of refraction has been modified along an desired optical path. EM and electrical connections between IGCs can be formed after the IGCs are bonded together to form the IGS. Use of an IGS as a vacuum boundary can provide substantial functionality for manipulating and interrogating quantum particles; the functionality can include, for example, the ability to regulate fields within the UHV cell.

    摘要: A process for manufacturing custom optically active quantum-particle cells includes forming a pre-customization assembly and then, in response to receipt of specifications for quantum-particle cells, performing a customization subprocess on the pre-customization assembly to yield custom quantum-particle cells, e.g., vapor cells, vacuum cells, micro-channel cells containing alkali metal or alkaline-earth metal ions or neutral atoms. The customization can include forming metasurface structures on cell walls, e.g., to serve as anti-reflection coatings, lenses, etc., and introducing quantum particles (e.g., alkali metal atoms). A cover can be bonded to hermetically seal the assembly, which can then be diced to yield plural separated custom optically active quantum-particle cells.

    摘要: A vacuum cell provides for electric field control within an ultra-high vacuum (UHV) for cold-neutral-atom quantum computing and other quantum applications. Electrode assemblies extend through vacuum cell walls. Prior to cell assembly, contacts are bonded to respective locations on the ambient-facing surfaces of the walls. Trenches are formed in the vacuum-facing surfaces of walls and via holes are formed, extending from trenches through the wall and into the contacts. Plating conductive material into the trenches and via holes forms the electrodes and vias. The electrodes are contained by the trenches and do not extend beyond the trenches so as to avoid interfering with the bonding of components to the vacuum-facing surfaces of the walls. The vias extend into the contacts to ensure good electrical contact. An electric-field controller applies electric potentials to the electrodes (via the contacts) to control electric fields within the vacuum.

    摘要: A probe laser beam causes molecules to transition from a ground state to an excited state. A control laser beam causes molecules in the excited state to transition to a laser-induced Rydberg state. Microwave lenses convert a microwave wavefront into respective microwave beams. The microwave beams are counter-propagated through molecules so as to create a microwave interference pattern of alternating maxima and minima. The microwave interference pattern is imposed on the probe beam as a probe transmission pattern. The propagation direction of the microwave wavefront can be determined from the translational position of the probe transmission pattern; the intensity of the microwave wavefront can be determined by the intensity difference between the minima and maxima of the probe transmission pattern.

    摘要: A laser system provides a system output signal and a monitor signal with a predetermined phase and/or frequency relationship to the system output signal. The monitor signal is combined with a reference frequency to yield an optical beat-note. A telecom optical transceiver (e.g., an SFP or an SFP+ module) is used to convert the optical beat-note to an analog electrical beat-note. The transceiver can extract received-power information from the analog electrical beat-note and digitize the analog electrical beat-note to yield a digital electrical beat-note. The digital electrical beat-note can be used to stabilize the laser and the system output signal by phase or offset locking.

    摘要: A shaken-lattice station and a cloud-based server cooperate to provide shaken lattices as a service (SLaaS). The shaken-lattice station serves as a system for implementing “recipes” for creating and using shaking functions to be applied to light used to trap quantum particles. The cloud-based server acts as an interface between the shaken-lattice station (or stations) and authorized users of account holders. To this end the server hosts an account manager and a session manager. The account manager manages accounts and associated account-based and user-specific permissions that define what actions any given authorized user for an account may perform with respect to a shaken-lattice station. The session manager controls (e.g., in real-time) interactions between a user and a shaken-lattice station, some interactions allowing a user to select a recipe based on results returned earlier in the same session.

    摘要: A quantum computer system packs quantum circuits into quantum memory so the circuits can be run concurrently. A quantum-circuit packer includes a resource mapper and a packing evaluator. The resource mapper characterizes the task of identifying candidate packings of pending quantum circuits as an integer linear problem (ILP), for which solutions are known. The packing evaluator applies an optimization criterion to select an optimum packing from the candidate packings. The optimum packing is run; the results are assigned to respective circuits that make up the packing.

    摘要: A quantum-sensing radiofrequency (RF) receiver system includes a multi-channel single-cell detection cell containing rubidium 87 atoms. Each channel is tuned to a respective RF frequency by applying electric potentials to indium-titanium-oxide (ITO) electrodes formed on detection cell walls. The channels are tuned to different RF frequencies to provide a relatively wideband detection in the aggregate across plural channels. A laser system provides plural laser beams, including a respective probe beam, to each channel to excite the 87Ru atoms therealong to a Rydberg state. Each channel can be read out by tracking absorption for each of the plural probe beams of the multi-channel system.

    摘要: A quantum-mechanics station (Ψ-station) and a cloud-based server cooperate to provide quantum mechanics as a service (ΨaaS) including real-time, exclusive, interactive sessions. The Ψ-station serves as a system for implementing “recipes” for producing, manipulating, and/or using quantum-state carriers, e.g., rubidium 87 atoms. The cloud-based server acts as an interface between the station (or stations) and authorized users of account holders. To this end, the server hosts an account manager and a session manager. The account manager manages accounts and associated account-based and user-specific permissions that define what actions any given authorized user for an account may perform with respect to a Ψ-station. The session manager controls (e.g., in real-time) interactions between a user and a Ψ-station, some interactions allowing a user to select a recipe based on wavefunction characterizations returned earlier in the same session.
